7... d5c4 A principled reaction, played after a long reflection. One feature of Ding's style is that he's not afraid to go for complicated and forcing variations, even when he might face advanced preparation. 8. e2e4 Officially a new move. This is obviously White's idea 7.Re1. 8... c8g4 A good reaction, pinning the knight and exerting pressure on the center. 9. b1d2 The first choice of the computer. Gukesh was still following his preparation. The knight attacks c4 and also prepares to capture on f3. 9... c6c5 A surprising move, probably played in order to take Gukesh out of his preparation.
